Inside the experimental cemetery.

Four figures stood in front of an empty wall.

The first one is a 5-meter-tall tree with a bathtub full of water on its head.

Supporting with two paws, the body is straight.

The second one was Liu Xiaodi, who had a basin of water on his head and was holding it with both hands.

The third and fourth ones are the two cubs of the little tree, with two teacups on their heads respectively.

Standing in a row, standing as a punishment! They stared at the man in white in the field.

Liu Di's voice came, "Branch, Leaf, you two did nothing wrong, you don't have to stand there."

The two little cubs looked at the little tree in confusion. They didn't know what was going on. Anyway, the atmosphere had been very serious since their owner came back.

The little tree growled.

The two cubs were so clumsy that they dropped the teacups above their heads and broke them into pieces. They slowly crawled to Liu Di's side, declared their affiliation with one camp, and immediately looked at Liu Xiaodi with a scrutinizing eye.

"Um"

Liu Di weighed the broom in his hand and swung it vigorously! Snap! The broom broke in midair!

Brother Liu said to himself, "It's not handy."

Afterwards, Brother Liu found another mop.

Snap! The mop broke again!

"This is the minimum power I can control, but it still doesn't work!"

Liu Di shook his head and found a chair. Bang! He threw the chair and it broke into pieces!

There was no other way, so Brother Liu had to find a large metal wrench, which was more than one meter long! He swung it, and with a crisp sound, the wrench broke in half! The little boy's face twitched, and he was shrouded in fear. He smiled stiffly and said, "Violent Bear, I don't think there are any tools that you can use in this room. Why don't you find a magic weapon one day and then enforce this family law that can be completely ignored, hehe."

Brother Liu shook his head. "I paid the school nearly five million today. Fortunately, Duan Hua helped to appease the principal, and fortunately, the children's parents did not believe in the existence of the little tree!"

As Brother Liu spoke, he slowly pulled out a 3-meter-long steel bar, as thick as a bowl!

Brother Liu was stunned. Are they trying to silence me?

Demon Child: "Brother Liu, you can't control your basic power now."

"According to my calculations, if I want to make little brother Liu's butt reach the appropriate level of blooming, he must wear my little vest of hell!"

Liu Di thought, "I just want to scare him, I can't really hit him."

Demon Child: "Then put it on slowly."

“Good idea.”

Brother Liu nodded and came to the side of the mechanical assembly line on the site, where there was a 3D printing warehouse.

Often used in the manufacture of mechanical parts.

Brother Liu was slightly stunned when he saw the Hell Leather Armor in the printing room! It was no longer a piece of clothing.

And the meridians in the human body, at a general glance, also look like the shape of a human body!

Brother Liu looked carefully.

These complex meridians are actually thin metal sheets, all of which are winding and at right angles, with chip modules embedded here and there!

The demon boy's voice was somewhat excited. "Now, let me introduce to you my Hell Leather Armor 2.0!"

"It is an upgrade from the world's leading technology 'electronic tattoo'!"

"It is actually an ultra-thin circuit that can be directly attached to the surface of the human body, with its own power supply and regulation module!"

"For you, it can control your muscle strength from 0.001-100%!"

"For others, it can monitor health data such as heart rate and blood pressure, and realize functions such as skin mobile phone and portable computing computer!"

"If it is connected to the human brain-computer interface, it will also become a little magic child!"

Brother Liu narrowed his eyes and nodded repeatedly.

This electronic skin will definitely become a major trend in the development of human technology in the future!

It will replace mobile phones, surpass virtual screens, and slowly become the ultimate wearable device for humans! Mo Tong added: "However, this requires a thorough understanding of the secrets of the human brain and the realization of a brain-computer interface before it can be achieved! Now I can only control it through network signals!"

Liu Di thought for a moment, "Demon boy, aren't you connected to my brain nerves?"

"Um"

"I am just a weak AI now. Although I can implement this technology, I don't know what's going on!"

Liu Di couldn't help but think of the signature on the Mo Tong program code - Emperor Jiu.

The name was confusing and he couldn't figure it out.

Liu Di sighed slightly, "The development of human technology still needs to proceed step by step. Gemini's wearable virtual screen is more suitable as the next innovation of mankind."

Magic Child: "The technological leap of electronic tattoos is indeed a bit too big, but technology has always been close to theology, just like people 50 years ago would not believe in today's smartphones. They would never have dreamed that this small square could connect the entire world!"

Then.

Brother Liu opened the door of the warehouse and prepared to put on the 'Hell Leather Armor 2.0! ' which was two levels higher than the public technology.

Ding, ding, ding! At this moment, there was a knock on the door, the sound was soothing and polite.

The scene outside the door suddenly appeared in Liu Di's perspective, and he was slightly startled.

He slowly passed by two figures carrying basins of water in the corner.

Push open the door.

There is no mistake in the poem, post, content, and read the book on 6, 9, and bar!

Outside the door stood a handsome young man wearing a black classical robe and short hair.

"Mr. Liu, I am a disciple of the Mo family, Mo Lan."

The smiling young man in front of him was none other than the Mohist disciple who had once guarded Mr. Song.

Brother Liu nodded slightly.

Mo Lan continued, "I am here to send you an invitation under the order of the eldest son of my family."

As he spoke, he handed over an exquisite wooden box, about the size and thickness of a book.

“You can open it and take a look.”

Mo Lan always maintained a polite smile.

invitation?

Brother Liu smiled calmly, not afraid of what was coming.

Slowly opening the wooden box, he saw a smooth silver metal cube inside, which was very exquisite.

Brother Liu played with it in his hands.

I discovered that this is a classic Chinese mechanical game - Huarong Dao.

It, along with Tangram and Nine Links, is called "Three Wonders in the World of Intelligence Games" by foreign intelligence experts! In the metal frame, there are several square chess pieces inlaid, and Cao Cao is trapped in the innermost part. Players need to move other squares to make Cao Cao break out.

Mo Lan smiled and said, "Mr. Liu, the 'Cao Cao' is the invitation card sent to you by the eldest son of your family. You can use your intelligence to get it out."

"But I want to remind you that the ordinary Huarong Road only has ten chess pieces, while my Mohist version is used by the master to play with on a daily basis, with a total of 52 chess pieces."

"certainly."

Mo Lan looked at him with deep meaning, "If you don't want to follow the etiquette, you can also use brute force to destroy it!"

Devil Child: "Wow, 52 chess pieces, theoretically there are 52 to the 52th power changes, multiplied by 4 moving positions!"

"The Mohist master is really unconventional. He sent out invitations in this way? Brother Liu held the Huarong Dao, slowly put it behind his back, and said with a smile: "But don't worry, using brute force is not worthy of this ancient Chinese civilization."

"The master has recently come out of seclusion and will stay for about a month. I wonder if Mr. Liu can come and visit him?"

Mo Lan chuckled.

There was something hidden in his words. If Brother Liu couldn't crack the 52-step Huarong Dao within a month, he would not even be qualified to meet the master!

Liu Di smiled calmly, "It should be possible."

Mo Lan nodded immediately, "Then I'll take my leave."

But the next moment.

Mo Lan, who was about to turn around, frowned slightly.

I heard a dense sound coming from Liu Di's hands behind his back! Kakaka! He was pushing the Huarong Dao chess piece rapidly! And the sound had formed a straight line! Very fast! Faster than human speed!

Mo Lan was a little surprised!

But after a few seconds!

I saw Brother Liu stretch out his hands.

The Huarong Dao in his hand emitted heat due to high-speed friction!

And the 'Cao Cao' chess piece has been taken out by Liu Di and placed flat in his palm!
